ABSTRACT
This data release provides digital versions of Oregon’s tsunami regulatory line and supplemental georeferenced digital scans of the official regulatory paper maps. In 1995 the Oregon Department of Geology and Mineral Industries (DOGAMI) created the official tsunami regulatory maps for implementing Oregon Revised Statutes (ORS) 455.446 and 455.447. These statutes were enacted as a result of Oregon Senate Bill 379 resulting in the commonly used reference “SB 379 maps” and “SB 379 line.” The official regulatory line is shown on paper maps published by DOGAMI. These paper maps depict the line in red on a black and white U.S. Geological Survey topographic basemap. GIS users often need to show a non-regulatory version on maps or to use a polygon version for GIS analysis. DOGAMI has created an unofficial but accurate vector line and polygon version of the regulatory line, and this publication makes those data available. Extra care was taken by DOGAMI to note line artifacts or errors resulting from map edges where the tsunami regulatory line is not reflected. This publication also includes georeferenced digital images of the regulatory maps that were used to create the vector data. Details on the processing steps used to create these products are provided in this report.
